Can I make the cake layers in advance?

Yes, you can bake the layers up to two days before your event. Wrap them tightly in plastic wrap once they are completely cool and store them at room temperature or in the refrigerator. This allows the flavors to settle and makes the cake easier to trim if necessary.

What is the best way to store leftovers?

If you have any cake remaining after the celebration, store it in an airtight container in the refrigerator for up to three days. Bring it back to room temperature before serving so the buttercream softens and the fork can glide through the layers. The crumb will remain moist thanks to the sour cream in the batter.

How do I ensure the cake doesn't stick to the pan?

Properly greasing and flouring your pans is essential for a clean release. You may also want to place a circle of parchment paper at the bottom of each pan for extra security. This small step ensures that your delicate layers remain intact when you turn them out.

Can I use whole eggs instead of just whites?

Using whole eggs will result in a more yellow cake with a slightly different texture and flavor profile. The egg whites are specifically used here to keep the cake snowy white and exceptionally light. If you swap them, the cake will be richer but slightly denser.

Is American buttercream the best choice for a smash cake?

American buttercream is preferred because it is stable and holds its shape well for decorations like roses. It is also very easy for a child to 'smash' because it remains soft at room temperature. The addition of salt and vanilla ensures it tastes wonderful without being overly sugary.

Can this recipe be frozen for later use?

The un-frosted cake layers freeze beautifully for up to one month. Wrap each layer individually in several layers of plastic wrap and then a layer of foil. Thaw them overnight in the refrigerator before you plan to stack and decorate the cake.

Instructions

Prepare the workspace. Preheat oven to 350F and grease four six-inch cake pans with butter and flour, then soak cake strips in water.
Sift dry ingredients. Combine flour, sugar, baking powder, baking soda, and salt in a bowl, whisking until the mixture is uniform and aerated.
Whisk liquid ingredients. Blend room temperature butter, warm milk, sour cream, vanilla extract, and vanilla bean paste, then gently fold in the egg whites.
Combine and bake. Slowly whisk the dry mixture into the wet ingredients, divide into pans, and bake for thirty-five to forty minutes until golden.
Whip the buttercream. Beat softened butter with confectioner’s sugar, vanilla, and a pinch of salt until light, fluffy, and cloud-like.
Create strawberry infusion. Fold strained strawberry preserves into a portion of the buttercream to achieve a pink hue and berry flavor.
Assemble the cake. Pipe strawberry buttercream between cooled cake layers, apply a thin crumb coat of plain frosting, and chill to set.
Apply final decorations. Smooth the remaining white buttercream over the cake and pipe floral accents using pink and matcha-tinted frosting.

Notes

Use a kitchen scale to ensure even layers for a perfectly balanced stack.
Bring all dairy ingredients to room temperature before mixing to prevent batter curdling.
Chill the cake after applying the crumb coat to ensure a stable structure for final decorating.
Use a hot metal scraper when applying the final buttercream layer for a professional, glossy finish.
Fold the batter gently to avoid developing excess gluten, which keeps the crumb tender.
